My son is 16 weeks and last week started moving around in his bedside crib - it is the Troll crib which has slatted sides. He woke himself up crying because he had rolled onto his side and got both legs stuck in the slats. We don't want to move him into his own room yet either. Our solution was to put the travel cot in our bedroom - it has mesh sides, so if he rolls up against them it is not so dangerous, and is easier to fit into our room than the cotbed. We're also putting a Sleepyhead inside it to stop him rolling about, but think it would probably be okay without this...
